Description
Die Erfindung betrifft eine Schließvorrichtung nach dem Oberbegriff des Anspruches
1. Eine derartige Schließvorrichtung ist aus der GB 2 271 863 A bekannt. Dabei wird
die Bewegungsgeschwindigkeit eines Fensters erfaßt. Sobald die Bewegungsgeschwindigkeit
unter einen vorbestimmten Grenzwert sinkt, wird dies als Einklemmen
eines Hindernisobjektes interpretiert, worauf ein Sicherheits-Regelungsbetrieb
durchgeführt wird, der die Fensterscheibe in Öffnungsrichtung bewegt.The invention relates to a locking device according to the preamble of the
Eine Automatisierung von Schließvorrichtungen fördert einerseits die Bequemlichkeit, birgt andererseits aber die Gefahr von Verletzungen. Dies gilt insbesondere für Schließvorrichtungen bei Kraftfahrzeugen, da sich der Fahrzeugführer beim Fahren primär auf den Verkehr konzentriert und durch leichtfertiges oder ungewolltes Betätigen der Schließvorrichtung für sich und seine Mitfahrer eine nicht unerhebliche Gefährdung auslösen kann. So ist es leicht möglich, daß beim Schließen eines Fensters oder Schiebedachs Körperteile eingeklemmt und ggf. auch verletzt werden.Automation of locking devices on the one hand promotes convenience, on the other hand harbors the risk of injury. This applies in particular to Locking devices in motor vehicles, since the driver is driving primarily focused on traffic and by careless or unwanted operation the locking device for himself and his passengers a not inconsiderable risk can trigger. So it is easily possible that when you close a window or sunroof body parts get trapped and possibly injured.
Bekannt sind Schließvorrichtungen, die den Motor direkt oder über Schaltverstärker, wie Relais und Leistungshalbleiter schalten. Um Verletzungen zu vermeiden, hat man bereits in den Rahmenteilen einer Öffnung, die durch ein Verschlußteil, also z. B. eine Scheibe oder ein Schiebedach geschlossen wird, Drucksensoren angebracht. Diese sorgen bei partiellem, auf nur einige Drucksensoren ausgeübtem Druck für ein Umschalten des Motorstroms in Öffnungsrichtung, so daß die Einklemmsituation selbsttätig wieder behoben wird. Locking devices are known which directly or via switching amplifiers, how to switch relays and power semiconductors. To avoid injuries one already in the frame parts of an opening through a closure part, ie z. B. a pane or a sunroof is closed, pressure sensors attached. These provide for partial pressure exerted on only a few pressure sensors Switching the motor current in the opening direction so that the pinching situation is automatically remedied.
Nachteilig an dieser Ausführung ist, daß die voreilenden, bzw. die Sensoren überragenden Lippendichtungen an den Rahmenteilen ein sicheres Reversieren des Motorstroms verhindern, da die Drucksensoren zu tief in den Rahmenteilen liegen und dadurch häufig zu spät ansprechen.A disadvantage of this design is that the leading or the sensors protrude Lip seals on the frame parts ensure safe reversing of the motor current prevent since the pressure sensors are too deep in the frame parts and thereby often speak too late.
Aufgabe der Erfindung ist es, eine Schließvorrichtung nach dem Oberbegriff des Anspruchs
1 so zu verbessern, daß Verletzungen bei unbeabsichtigter oder leichtsinniger
Betätigung der Schließfunktion sicher vermieden werden.The object of the invention is a locking device according to the preamble of the
Diese Aufgabe wird durch die in Anspruch 1 gekennzeichneten Merkmale gelöst.
Zweckmäßige Ausgestaltungen und Weiterbildungen des Erfindungsgegenstandes
sind in den Unteransprüchen genannt.This object is achieved by the features characterized in
Erfindungsgemäß ist im Bereich der Öffnung zwischen dem Verschlußteil und einem die Öffnung begrenzenden Rahmen eine aus mehreren, in geeigneten Abständen zueinander angeordneten Sensoren bestehende Sensorreihe so angeordnet, daß diese bei geöffneter Öffnung außerhalb des Wirkbereiches der Dichtlippen einer das Verschlußteil bei geschlossener Öffnung erfassenden Dichtung liegt. Die Dichtlippen überragen somit die Sensoren nicht oder nur unwesentlich und behindern dadurch nicht das Ansprechen der Sensoren im Fall des Einklemmens eines Körperteils. Die aktivierten Sensoren wirken auf eine Logikschaltung ein, die aufgrund der aktivierten und nicht aktivierten Sensoren eine Plausibilitätsprüfung vornimmt, mit der Gefahr signalisierende Aktivierungen erfaßt und so ausgewertet werden, daß im Gefahrenfall die Reversierschaltung die Stromflußrichtung des Motorstromes umschaltet.According to the invention is in the region of the opening between the closure part and one the opening delimiting frame one of several, at suitable intervals mutually arranged sensors existing sensor array arranged so that this with the opening open outside the effective range of the sealing lips Closure part lies with the seal covering the opening closed. The sealing lips Thus, the sensors do not protrude, or only insignificantly, and thus hinder not the response of the sensors in the event of a part of the body being caught. The activated sensors act on a logic circuit which, due to the activated and not activated sensors carries out a plausibility check with the danger signaling activations are recorded and evaluated so that in the event of danger the reversing circuit switches the current flow direction of the motor current.
Besonders vorteilhaft an der erfindungsgemäßen Schließvorrichtung ist, daß sie mit einfachen Mitteln aufgebaut ist und die Plausibilitätsprüfung so gestaltet werden kann, daß Gefahrenzustände sicher erfaßt werden.A particular advantage of the locking device according to the invention is that it can be operated with simple means is built and the plausibility check is designed in this way can ensure that dangerous conditions are detected reliably.
Ein besonders kostengünstiger Aufbau der Schließvorrichtung läßt sich erzielen, wenn die Sensorreihe auf der in Verschlußrichtung liegenden Schließkante des Verschlußteils befestigt ist. Hierbei können die Sensoren in einem vorgefertigten Streifen, der z. B. als Schaltmatte mit einer Vielzahl einzelner Kontaktgeber und mit deren Zuführungsleitungen ausgebildet ist. Eine derartige Schaltmatte kann auf die Schließkante aufgeklebt und über eine flexible Leitung mit der Logikschaltung verbunden werden.A particularly cost-effective construction of the locking device can be achieved if the row of sensors on the closing edge of the closing part lying in the closing direction is attached. Here, the sensors can be placed in a prefabricated strip, the z. B. as a switching mat with a large number of individual contactors and their Feed lines is formed. Such a safety mat can on The closing edge is glued on and connected to the logic circuit via a flexible cable become.
Eine alternative zweckmäßige Ausgestaltung der Erfindung sieht vor, die Sensorreihe auf der in Verschlußrichtung liegenden Schließkante des Rahmens zu befestigen. Auch hierbei können die Sensoren in einem vorgefertigten Streifen liegen und auf die Schließkante aufgeklebt und über eine Leitung mit der Logikschaltung verbunden werden.An alternative expedient embodiment of the invention provides the sensor series to be fastened on the closing edge of the frame in the direction of closure. Here, too, the sensors can lie in a prefabricated strip and on the Closing edge glued on and connected to the logic circuit via a cable become.
Damit jedoch die Dichtlippen der Dichtung eine Aktivierung der Sensoren im Gefahrenfall nicht behindern, ist es vorteilhaft in weiterer Ausbildung des Erfindungsgegenstandes dafür zu sorgen, daß die Sensoren von der Schließkante des Verschlußteils aktiviert werden können, bevor die Dichtlippen wirksam werden. Hierzu sind die Sensoren der Sensorreihe so angeordnet und/oder ausgebildet, daß sie beim Zusammentreffen mit der Schließkante des Verschlußteils zunächst eine Signalgabe auslösen und dann in den Dichtungsspalt zwischen die Dichtlippen der Dichtung entgegen einer Federkraft hineingedrückt werden. Beim Öffnen des Verschlußteils sorgen die Federkräfte dafür, daß die Sensoren wieder in ihre gegenüber den Dichtlippen voreilende Stellung zurückbewegt werden.However, this means that the sealing lips of the seal activate the sensors in the event of danger does not hinder, it is advantageous in further training of the subject of the invention to ensure that the sensors from the closing edge of the closure part can be activated before the sealing lips take effect. The sensors are for this the row of sensors arranged and / or designed so that they meet Initiate a signal with the closing edge of the closure part and then into the seal gap between the sealing lips of the seal be pressed in by a spring force. When opening the closure part ensure Spring forces ensure that the sensors lead back into their leading lips Position can be moved back.
Zur Realisierung der Logikschaltung besteht eine Vielzahl von Möglichkeiten, wobei gegebenenfalls auch ein Prozessor zum Einsatz gelangen kann. Eine dieser Möglichkeiten besteht darin, die Plausibilitätsprüfung aufgrund der aktivierten und nicht aktivierten Sensoren so durchzuführen, daß die Logikschaltung einen Befehl zum Reversieren des Motors gibt, wenn beim Schließen des Verschlußteils mehr als eine untere Grenzzahl aber weniger als eine obere Grenzzahl aller Sensoren aktiviert sind. Die untere Grenzzahl könnte im Extremfall Null sein, so daß in diesem Fall mindestens ein Sensor aktiviert werden müßte, nicht aber alle Sensoren aktiviert sein dürfen, da das normalerweise nur bei geschlossenem Verschlußteil der Fall sein kann.There are a multitude of options for realizing the logic circuit if necessary, a processor can also be used. One of those ways consists of the plausibility check based on the activated and not activated sensors so that the logic circuit a command to Reversing the motor gives when closing more than one lower limit but less than an upper limit of all sensors activated are. In extreme cases, the lower limit number could be zero, so that in this case at least one sensor should be activated, but not all sensors should be activated may, as this is normally only the case when the closure part is closed can.
Eine Kontrolle, ob nicht bereits die Schließstellung des Verschlußteils erreicht ist, kann alternativ auch dadurch erfolgen, daß die Aktivierung bestimmter Sensoren ermittelt wird. Sind z.B. zwei Sensoren aktiviert, von denen sich der eine in einer linken und der andere in einer rechten Extremlage befindet, so können diese gemeinsam nur durch das Verschlußteil in seiner Schließstellung aktiviert worden sein.Checking whether the closure part has not already reached the closed position, can alternatively also take place by determining the activation of certain sensors becomes. Are e.g. two sensors activated, one of which is in a left and the other is in a right extreme position, these can be together only be activated by the closure part in its closed position.
Die Reversierschaltung ist in vorteilhafter Weise so aufgebaut, daß das von der UND-Logik kommende Signal ggf. über ein Zeitglied verzögert einer Steuereinheit zugeführt wird, die ihrerseits die Stromflußrichtung des Motorstroms umschaltet.The reversing circuit is advantageously constructed so that the AND logic incoming signal delayed by a control unit, possibly via a timing element is supplied, which in turn switches the direction of current flow of the motor current.
Weiterhin ist es zweckmäßig die Schließvorrichtung so aufzubauen, daß in Reihe zu dem über die Steuereinheit mit Strom versorgten Motor ein Meßwiderstand des Meßwertgrenzsignalgebers liegt.Furthermore, it is advisable to build the locking device so that in series the motor supplied with current via the control unit has a measuring resistor of Measured value limit signal transmitter.
Ein Taster besitzt eine Umschalttastfunktion und führt in Abhängigkeit von der Tastrichtung Minus- oder Pluspotential dem Eingang der Steuereinheit zu, wobei diese ihrerseits die Stellrichtung des Motors entsprechend verändert.A button has a toggle button function and is dependent on the direction of the button Minus or plus potential to the input of the control unit, this in turn changed the direction of the motor accordingly.
Ein zum Meßwert-Grenzsignalgeber gehöriger Komparator vergleicht den Spannungsabfall des Motorstroms am Meßwiderstand mit einer Referenzspannung und führt sein hiervon abhängiges Ausgangssignal der UND-Logik zu. Zwei in Reihe zwischen Plus- und Minuspotential liegende Widerstände erzeugen die zwischen ihnen abzugreifende Referenzspannung.A comparator belonging to the measured value limit signal compares the voltage drop the motor current at the measuring resistor with a reference voltage and leads its dependent output signal to the AND logic. Two in a row between Plus and minus potential resistances create the between them reference voltage to be tapped.
Der erläuterte Aufbau der Schließvorrichtung mit logischen Bauelementen kann nur eine der vielfältigen Lösungsmöglichkeiten im Sinne des Erfindungsgedankens verdeutlichen. Eine gleichartige Wirkungsweise kann auch unter Zugrundelegung anderer Potentialverhältnisse und mit anderen logischen Schaltelementen erzeugt werden.The described structure of the locking device with logical components can only clarify one of the many possible solutions in terms of the inventive concept. A similar mode of operation can also be based on others Potential relationships and are generated with other logic switching elements.

Wie Fig. 1 erkennen läßt besitzt die Schließvorrichtung eine Reversierschaltung RS, die es ermöglicht die Stellrichtung eines Motors M unter bestimmten Bedingungen umzukehren. Diese Bedingungen erlangen unter sicherheitstechnischen Aspekten nur in der Schließphase eine Bedeutung, da nur während dieser Zeit die Gefahr eines Einklemmens besteht, so daß während der Öffnungsphase keine Umkehrung der Stellrichtung des Motors M erforderlich ist. Der Motorstrom wird bei diesem Beispiel unmittelbar vom Steuerstromkreis aufgebracht, um die Darstellung und damit das Verständnis zu erleichtern. Selbstverständlich könnte der Motor M auch im Schaltkreis eines Relais oder Verstärkers liegen. Die Erzeugung des Motorstroms erfolgt mit Hilfe einer Spannungsquelle U1 über eine Steuereinrichtung SE, in der sich auch Betätigungsorgane befinden.1 shows the locking device has a reversing circuit RS, which enables the direction of adjustment of a motor M under certain conditions to reverse. These conditions are achieved from a safety point of view meaning only in the closing phase, since only during this time there is a risk of Pinching exists so that no reversal of the opening phase Setting direction of the motor M is required. The motor current is in this example applied directly by the control circuit to the representation and thus that To facilitate understanding. Of course, the motor M could also be in the circuit of a relay or amplifier. The motor current is generated with the help of a voltage source U1 via a control device SE, in which also Actuators.
Sollte beim Schließen des Fensters versehentlich ein Körperteil eingeklemmt werden, so wird mindestens einer von mehreren an Pluspotential liegenden, als Sensoren wirkenden Kontaktgebern KG1-KGn eines Stellungsgebers SG in seine Einschaltstellung gedrückt und aktiviert dadurch den zugehörigen Eingang einer nachgeschalteten ODER-Logik G3, die hierdurch ebenfalls aktiviert wird und den Eingang einer nachgeschalteten UND-Logik G1 mit High beaufschlagt. An ihrem zweiten Eingang erhält die UND-Logik G1 nur dann ebenfalls ein High, wenn mindestens ein Kontaktgeber KG1-KGn nicht eingeschaltet wurde. Hierzu ist der zweite Eingang der UND-Logik G1 mit dem Ausgang einer NAND-Logik G2 verbunden, deren Eingänge mit den Eingängen der ODER-Logik (G3) verbunden sind.If a body part is accidentally caught when the window is closed, so at least one of several positive potential sensors Acting contactors KG1-KGn of a position transmitter SG pressed into its switched-on position and activated thereby the associated input of a downstream OR logic G3, the this also activates and the input of a downstream AND logic High applied to G1. The AND logic receives G1 at its second input also only a high if at least one contactor KG1-KGn is not switched on has been. For this purpose, the second input of the AND logic G1 with the output a NAND logic G2, the inputs of which are connected to the inputs of the OR logic (G3) are connected.
Mit Hilfe der NAND-Logik G2 wird sichergestellt, daß in der Schließstellung zwangsläufig ausgelöste Sensoraktivierungen nicht als Gefahr interpretiert werden. Dies kann alternativ auch dadurch erfolgen, daß nur ganz bestimmte, sich in exponierter Lage befindende Sensoren von der NAND-Logik G2 erfaßt werden, die im Gefahrenfall nie aktiviert werden. Am prinzipiellen Schaltungsaufbau ändert sich hierdurch nichts, so daß sich eine Darstellung dieser Schaltungsvariante erübrigt.With the help of the NAND logic G2 it is ensured that in the closed position inevitably triggered sensor activations should not be interpreted as a hazard. This can alternatively also take place in that only very specific ones are exposed Position sensors are detected by the NAND logic G2 in the event of danger never be activated. This changes the basic circuit structure nothing, so that a representation of this circuit variant is unnecessary.
Die im Gefahrenfall aktivierte UND-Logik G1 gibt ein High-Signal ab, das einen zur Reversierschaltung RS gehörigen ersten "Auf-Eingang" einer Steuereinheit SE erreicht und ein Umschalten des Motorstroms bewirkt. Dementsprechend öffnet der Motor M das angetriebene Verschlußteil, also beispielsweise das Fenster wieder, und ermöglicht dadurch eine Freigabe ggf. eingeklemmter Körperteile.The AND logic G1 activated in the event of an emergency emits a high signal that leads to Reversing circuit RS belonging to the first "open input" of a control unit SE reached and causes switching of the motor current. The opens accordingly Motor M the driven closure part, for example the window again, and thereby enables any parts of the body that are trapped to be released.
Durch Bewegen eines Tasters S1 in seine rechte Einschaltstellung wird einem "Zu-Eingang" der Steuereinheit negatives Potential zugeführt, das ein Zurücksetzen in die Grundstellung bewirkt und damit ein erneutes Schließen des Fensters ermöglicht. By moving a button S1 into its right switch-on position, a "closed input" negative potential supplied to the control unit, which a reset in causes the basic position and thus enables the window to be closed again.
Die Steuereinheit SE muß so aufgebaut sein, daß einem Plussignal an seinem ersten "Auf-Eingang" Vorrang gegenüber einem Minussignal an seinem "Zu-Eingang" eingeräumt wird. Dies ist wichtig, damit bei einer Einklemmgefahr sich das Fenster automatisch wieder öffnet. Unabhängig von der automatischen Sicherheitsöffnung kann durch eine Bewegung des Tasters S1 von seiner Ruhelage in seine linke Einschaltstellung einem zweiten "Auf-Eingang" der Steuereinheit positives Potential zugeführt werden, so daß auch ein gezieltes Öffnen des Fensters von Hand möglich ist.The control unit SE must be constructed so that a plus signal at its first "Open input" given priority over a minus signal at its "closed input" becomes. This is important so that if there is a risk of being caught, the window will open automatically opens again. Regardless of the automatic security opening can by moving button S1 from its rest position to its left switch-on position positive potential is fed to a second "open input" of the control unit be, so that a targeted opening of the window by hand is possible.

Fig. 2 erkennt man in einer Autotür 1 eine als Verschlußteil 2 wirkende Fensterscheibe,
die beim Schließen einer Öffnung 12 in ihrer Schließstellung auf einen als
Sensor wirkenden Kontaktgeber trifft. Es handelt sich hierbei um einen von mehreren
auf einer Schließkante eines Rahmens 6 befestigten Kontaktgebern KG1-KGn. Jeder
von ihnen besitzt eine Kontaktfeder 3, ein als Kontaktbrücke wirkendes bewegliches
Kontaktteil 4 und zwei durch die Kontaktbrücke zu verbindende Einzelkontakte 5. Als
Besonderheit ist außerdem jeder Kontaktgeber so angeordnet und aufgebaut, daß er
nach einer Kontaktgabe von der Fensterscheibe 2 noch weiter in den Rahmen 6 hineingedrückt
wird. Hierzu sind die Einzelkontakte 5 auf einer Isolierplatte 14 befestigt,
die ihrerseits einen Führungszapfen 15 besitzt und durch Zusammenpressen einer
Druckfeder 16 eine Bewegung ermöglicht. Durch diese zusätzliche Bewegung ist es
dem zwischen den Dichtungslippen einer Dichtung 7 liegenden Kontaktgeber möglich,
unbehindert durch die Dichtlippen, Kontakt zu geben aber auch andererseits die
Dichtlippen in ihrer Wirkung nicht zu behindern.2 to 4 show various mechanical parts of the locking device. At

- A closing apparatus for the automatic closing of openings (12) by a motor-driven closing part (2) with a safety circuit which for the protection of body parts during the signalization of a squeezing hazard acts on the motor (M) in such a way that the same prevents any squeezing by reversing its running direction, characterized in that in the zone of the opening between the closing part (2) and a frame (6) limiting the opening, a row of sensors (13) which consists of several sensors (KG1-KGn), preferably simple contact makers, which are arranged at suitable distances from one another is arranged in such a way that when the opening is opened (12) the same is disposed outside of the effective range of sealing lips of a seal (7) grasping the closing part (2) when the opening (12) is closed and that the sensors (KG1-KGn) act upon a logic circuit which performs a plausibility check as a result of the activated and not activated sensors (KG1-KGn) with which activations are detected which signalize a hazard and are evaluated in such a way that in the event of a hazard the reversing circuit (RS) changes the direction of current flow of the motor current.
- A closing apparatus as claimed in claim 1, characterized in that the row of sensors (13) is fastened to the closing edge of the closing part (2) which is disposed in the closing direction.
- A closing apparatus as claimed in claim 1 or 2, characterized in that the row of sensors (13) is fastened to the closing edge of the frame (6) which is disposed in the closing direction.
- A closing apparatus as claimed in claim 3, characterized in that the sensors (KG1-KGn) of the row of sensors (13) which preferably consist of simple switching elements are disposed and/or arranged in such a way that on meeting with the closing edge of the closing part (2) they initiate a signaling and are then pressed into the sealing gap between the sealing lips of the seal (7) against a spring force.
- A closing apparatus as claimed in one of the claims 1 to 4, characterized in that the plausibility check is performed as a result of the activated or not activated sensors (KG1-KGn) in such a way that the logic circuit issues a command for reversing the motor when during the closing of the closing part (2) more than one lower limit, which can also be zero, but less than one upper limit of all sensors (KG1-KGn) are activated.
- A closing apparatus as claimed in one of the claims 1 to 4, characterized in that the plausibility check is performed as a result of the activated or not activated sensors (KG1-KGn) in such a way that the logic circuit issues a command for reversing the motor when during the closing of the closing part (2) at least one sensor (KG1-KGn) is activated, but certain sensors (KG1-KGN), which usually can only be activated in the closed position of the closing part (2), are not activated.
- A closing apparatus as claimed in claim 5, characterized in that several sensors (KG1-KGn) are connected on the one hand with the inputs of an OR logic circuit (G3) and on the other hand with the inputs of a NAND logic circuit (G2) and the outputs of these two logic elements (G2, G3) are connected with the input of an AND logic circuit which on its part issues a high signal when at least one sensor (KG1-KGn) is activated but not all sensors (KG1-KGn) are activated.
- A closing apparatus as claimed in claim 6, characterized in that several sensors (KG1-KGn) are connected with the inputs of an OR logic circuit (G3) and only a few specific sensors which can only be activated in the closed position of the closing part (2) are connected with the inputs of a NAND logic circuit (G2), and the outputs of said two logic elements (G2, G3) are connected with the input of an AND logic circuit (G1) which on its part issues a high signal when at least one sensor (KG1-KGn) is activated, but the specific sensors which can be activated only in the closed position of the closing part (2) are not activated.
- A closing apparatus as claimed in claim 7 and 8, characterized in that an activated output of the AND logic circuit initiates a reversing of the motor (M).
- A closing apparatus as claimed in claim 9, characterized in that for reversing the motor (M) a reversing circuit (RS) is used which includes a control unit (SE) which based on a voltage source (U1) supplies the motor (M) with current and predetermines the direction of the motor current depending on the input signals supplied to the same, and that in the case of a simultaneous supply of both a plus and a minus signal, the control unit (SE) gives the signal which leads to the opening of the closing part (2) priority.
- A closing apparatus as claimed in one of the claims 1 to 10, characterized in that a measuring shunt of the measured-value limit transducer is disposed in the motor current circuit.
- A closing apparatus as claimed in claim 11, characterized in that a momentary-contact (S1) comprises a changeover contact function and, depending on the contact direction, supplies minus or plus potential to the input of the control unit (SE), as a result of which the same changes the position of the motor accordingly.
